Minkowski's Object (Arp 133)

A peculiar dwarf galaxy in the constellation Cetus
lying about one arc-minute ENE of the elliptical
galaxy NGC 541. The latter is also a radio
galaxy that has a jet of ionized plasma
emanating from its nucleus. Evidence now suggests that a burst of star
formation in Minkowski's Object (Arp 133) was actually triggered by
the jet from the nucleus of NGC 541 because the body of the jet can be traced
all the way to the region where the new stars are forming. If this turns
out to be true, it will be the first known case of a jet from one galaxy
influencing a neighboring galaxy and triggering new star birth. The details
of just how this could occur are uncertain.
